Some Advanced Configuration Menu Options
When you create the regions, define them by choosing names that reflect
what they are, like local users or perhaps mobile users for those using the IP
SoftPhone. Our site uses two regions, named like those in the previous sentence.

Next, create device pools which logically group the physical devices. Just like
regions, the names you create should define their device types. Nothing is needed
to configure the device pool. It is just a logical group, like Windows NT’s Global
Groups or Netware’s Groups, to which you can later add devices.You can then add
device pools to a region so they are treated with a specific type of compression.
One other setup task is called locations, which is merely a definition of where
a device will reside. Since CCM can handle huge numbers of users, both local
and mobile, CCM administrators often use this tool to group sites by their geographical
location. Let’s say that CCM is located in Atlanta and serves 25 users,
but Charlotte, Raleigh,Tampa, and Miami all have 5 users per site.You can create
locations for all these sites, which give you the ability to control how these users
access the system.
Next, go into the CCM system configuration and define the range of phone
numbers the site will use.The default is the range 6000 through 6999, but you
can add more ranges as needed.You should always, however, be cognizant of
other site needs, so you don’t run out of numbers, or create duplication of numbers
between sites. Many CCM administrators reserve the 6000 through 6099
numbers for desktop IP phones, 6100 through 6199 for IP SoftPhones, as well as
other series.
Now, go into the Device section of CCM and add a new phone (see Figure
10.13).This will let you choose the type of phone, what region the phone will
reside in, as well as what phone number will be associated with the physical
phone. Lastly, we need to create the users in the CCM directory who require
these new resources.When a user is added, you must select a phone that will
become the user’s own phone.
Sometimes user/phone allocations will need to be changed—for instance, if
the user gave up his office to telecommute from home. In such cases, the user
would likely employ the Cisco IP SoftPhone on a laptop computer. So, instead of
assigning this person a new phone number, all you’d need to do is create a new
phone called a CTI point, (a Computer Telephony Instrument).This CTI point is
indeed the SoftPhone.You can go to the original 7960 phone and remove it from
service, then assign the original phone number to the new SoftPhone when the
user moves out of the office. In this manner, the user never loses their number,
nor their service.
